To @Mish/07;@ it mil-'iff concern:

Bo it known that l, Josnru Ori'rz, a citi- Zon of the United States, residing at New York, in the county of New York and State of New York, have inventcdn certain new and useful improvement in Terminal Connectors, of which the following is a lull, clear', conciso, and exact description. n

My invention relates to a terminal connector lor magnet-spools, resistauce-coils, and the like; and its object is to provide an ini proved construction which will be simple, ely lectivo, and cheap to inanuiac ture.

l will describe my invention particularly by reference to the accompanying drawings, and the` parts, improvements, or conibinations which l regard as novel uill be pointed out in the appended clainis. g

Vln tln\.drawings, Figure .l is a perspective view of a spool-head equipped with my iinprovod terminal conncctii'ig-pieoes. lP ig. 2 is a roar View ltirol-eral", showing the manner of securing the terminal pieces to the spoolhead or supporting-plato. Fig. 3 is a sec-- tional vieu' on lino il I3 of Fig. 2. Fig. 4 is a plan n ol a nuignot-coil equipped 'with niy iniprovcd terminal connecting pieces, and llig. 5 is a detail View o? one of the con.- ncctingpiccos taken out oll its mounting.

The saine letters of rclcrcnce are used to doi- 'girato thel saine parts in each of the liguros ol thcdrawings.

lsiagnot-spools and electrical coils in general lare usually provided with end plates or heads of insulating material, and my improved terniinal connectors are adapted to be fastened, directly to such terminal heads. The terniinal pieces arc Vniadc of llat metal punchings of rectangular cross-scclion, adapted to be passed through holes l) lr in the head or plato a. The rear end c of each terminal piece is turned at an angle to forni a laterallyn projecting oar, which is secured to the plate a, being embedded `lin a recess or socket in the rea-r l'nco oi said plate adjacent to the hole l) in the plate. The recess or socket opens oilE the hole l) at the rear oi the plato (L and is preferably made circular, so that it may be formed by drilling,` and the ear or turned-over end c oi the terminal connector is prelerably shaped to iit snugly into such circinar recess The shank ol the terminal piece is preler-- l ably widened at the rear Where it passes through the hole l) in the plate, so that while it niay be inserted easily through the hole until it is nearly in place the enlarged portion will inally Wedge tightly in the hole. The hole l) is preferably round, such as would be formed by drilling, and-the ilat punilhing or connectinT piece will not entirely plug up this hole, but will leave a space alongside the shank thereof through which. the end oi the wire of th e helix inay be passed.

lflhen the terminal connector of my invenl tion is applied to a coil, as illustrated in Fig. e, the terminal wires d dol the helix are any suitable Way, as by soldering, to the projecting Shanks of the terminal pieces or punchings c. TWhen the connector isthus placed upon the end of the spool, ythe presence ol the coil-winding back of the ears c c assists in holding the terminal pieces in place.

1. ln a terminal connector for a wire-spool the combination with the insulating-head ol' the spool, of a instal punching -passing through a hole in said head, the terminal wire of said spool passing through said hole and being secured to said punching, and an ear formed by the rear ond ol' said punching and secured to the rear face oi the insulatinghead. f

2. ln a terminal connector, the conibiiwt` tion with the insulatingsupporting-plate, ol a llat iuetal punching passing through a holo therein, a recess in the rear lace of said plato, and an ear formed by the rear end ol said punching and forced into said recess.

3. ln a terminal connector, tho combination with the insulating su}' portingplatc, of a flat metal punching passing through a hole therein, said hole being oi such size as to permit thc passage of a conducting-wire there.- through, the shank of the punching being widened where it passes through said hole, to wedge into the same, and an car formed by tho turned-over roar ond o said punching, said ear being forced into .a recess in the roar lace of the supporting-iplate.V

4. The combination With a Wire coil,.ol" au insulatingplate forlninfy one of the heads of the ooihspool, fiat nieta. punchings or termi nal pie-ces passing through round holes in said plate, the terminal wires of said coil'ellso passed through the holes l; l) and secured IOO passing through said holes and being'secured to said metal punchings, and ears formed by,

the rear ends of said punchngs and secured to the inner face of said plate, the pressure of the coil-Winding assisting in holding said ears in lace,

5. T 1e combination with an insulating head-plate for coils, said plate having a round hole transversely through the same, and a circular recess in the rear face of said plate, opening from said transverse holo, of a terminal picco lormed of a flat metal punching wedged in saidhole from the rear, the rear end of said punching being rounded and bent angularly to form an ear fitting tightly in said circular recess.

6. In a terminal connector, the'combination with an insulating supporting-plate, of a flat metal unching passing through a hole therein and) extending away from said plate, said hole being of ay size to permit the passage of a conducting-wire therethrough, and an sulating-head an secured at' their rear ends to the'rear face of said head, the terminal wires of said spool passin lthrough said holes and being secured to sai punchings.

In Witness whereof I hereunto subscribe my name this 11th day of January, A. D.
